Claim 8

A stapler apparatus, comprising in combination, housing means including upper and lower cover members adapted to be fitted together to form a closed chamber, hinge means located adjacent the rear end of said housing means and interconnecting adjacent edges of said upper and lower cover members for permitting relAtive pivotal movement of said cover members away from one another, stapling means disposed within said housing means for permitting a staple to be injected into a selected article when said housing means is in an open condition, said stapling means including an upper pressing portion having a magazine adapted to contain a plurality of staples therein, said stapling means also including a base portion pivotally interconnected to said pressing portion for permitting relative pivotal movement between said magazine and said base portion, and means pivotally interconnecting said base portion relative to said lower cover member for permitting said lower cover member to be rotated away from said base portion and away from said upper cover member for permitting operation of said stapling means, said base portion being disposed within said lower cover member when said housing means is in a closed position.

Claim 9

A stapler apparatus, comprising in combination, housing means including upper and lower cover members adapted to be fitted together to form a closed chamber, hinge means located adjacent the rear end of said housing means and interconnecting adjacent edges of said upper and lower cover members for permitting relAtive pivotal movement of said cover members away from one another, stapling means disposed within said housing means for permitting a staple to be injected into a selected article when said housing means is in an open condition, said stapling means including an upper pressing portion having a magazine adapted to contain a plurality of staples therein, said stapling means also including a base portion pivotally interconnected to said pressing portion for permitting relative pivotal movement between said magazine and said base portion, and means pivotally interconnecting said base portion relative to said lower cover member for permitting said lower cover member to be rotated away from said base portion and away from said upper cover member for permitting operation of said stapling means, said base portion being disposed within said lower cover member when said housing means is in a closed position.

Claim 10

An apparatus according to claim 6, wherein said magazine and said base portion have their adjacent ends pivotally connected to said upper cover member adjacent the rear end of said housing for permitting said magazine and said base portion to pivotally move relative to one another and relative to said upper cover member, said stapling means also including a feeding mechanism disposed within said magazine for resiliently urging staples therealong toward the front end of said magazine, the front end of said base portion having anvil means formed thereon disposed for coaction with a staple ejected from said magazine for permitting said staple to be secured to said selected article, driving means coacting between said upper cover member and said magazine for ejecting the endmost staple from said magazine in response to relative pivotal movement of said upper cover member toward said magazine, first resilient means coacting between said upper cover member and said magazine for resiliently pivotally urging same away from one another into a normal inoperative position, and second resilient means coacting between said magazine and said base portion for resiliently pivotally urging same away from one another into a normal inoperative position.

Claim 11

An apparatus according to claim 7, wherein said upper and lower cover members are both constructed of plastic and have opposed channel-shaped configurations with the opposite edges of said cover members being disposed in engagement with one another when said housing means is in said closed position, said hinge means comprising a straplike plastic hinge integrally connected to the adjacent ends of said upper and lower cover members at the rear end of said housing means, the front ends of said cover members having coacting locking means formed thereon for releasably maintaining said housing means in said closed position, said upper and lower cover members respectively having upper and lower walls spaced apart by a substantial distance to enable said first and second resilient means to maintain said magazine and said base portion spaced apart in their normal inoperative position when said housing means is closed.

Claim 12
